All the predefined events are enabled by default. You can disable many of the events if necessary.

Some predefined events are referenced by default subscriptions that are created automatically when you install Oracle Workflow. The subscriber for all the default subscriptions is the local system. You can enable, disable, or copy many of these subscriptions to perform the event processing that you want.

Attention: You must not change or disable the definition of the Unexpected event or of the predefined Error subscription to that event. If you do, the Event Manager will not be able to perform default error handling for events and subscription processing.

Note: Predefined events and default subscriptions are also provided with some Oracle Applications and Oracle Self-Service Web Applications. For more information on Oracle Applications-specific workflow events, consult the documentation or help for that specific Oracle Application product.
